How to create a ColorspaceConversion function dataset

Creating a ColorspaceConversion function dataset

1. Create the Function Arguments object.
2. Set the type of conversion to be performed.
3. Create a Raster Function object.
4. Create a Function Raster Dataset object.
5. Specify the output file name for the new dataset.
6. Initialize the new function raster dataset with the raster function and its arguments.

[C#]

// Create the Function Arguments object.
IColorspaceConversionFunctionArguments rasterFunctionArguments=
    (IColorspaceConversionFunctionArguments)new
    ColorspaceConversionFunctionArguments();
// The input data can be of type IRasterDataset, IRasterBand, or IRaster.
rasterFunctionArguments.Raster=inputData;
// Set the type of conversion you want to perform.
rasterFunctionArguments.ConversionType =
    esriColorspaceConversionType.esriColorspaceConversionRGBToHSV;

// Create the Raster Function object.
IRasterFunction rasterFunction=new ColorspaceConversionFunction();
// Create the Function Raster Dataset object.
IFunctionRasterDataset functionRasterDataset=new FunctionRasterDataset();
// Create a name object for the Function Raster Dataset.
IFunctionRasterDatasetName functionRasterDatasetName=(IFunctionRasterDatasetName)
    new FunctionRasterDatasetName();
// Specify the output file name for the new dataset (including the .afr extension at the end).
functionRasterDatasetName.FullName=@"c:\temp\ColorspaceConversion.afr";
functionRasterDataset.FullName=(IName)functionRasterDatasetName;
// Initialize the new Function Raster Dataset with the Raster Function and its arguments.
functionRasterDataset.Init(rasterFunction, rasterFunctionArguments);

[VB.NET]

' Create the Function Arguments object.
Dim rasterFunctionArguments As IColorspaceConversionFunctionArguments
rasterFunctionArguments=New ColorspaceConversionFunctionArguments()
' The input data can be of type IRasterDataset, IRasterBand, or IRaster.
rasterFunctionArguments.Raster=inputData
' Set the type of conversion you want to perform.
rasterFunctionArguments.ConversionType=esriColorspaceConversionType.esriColorspaceConversionRGBToHSV

' Create the Raster Function object.
Dim rasterFunction As IRasterFunction
rasterFunction=New ColorspaceConversionFunction()
' Create the Function Raster Dataset object.
Dim functionRasterDataset As IFunctionRasterDataset
functionRasterDataset=New FunctionRasterDataset()
' Create a name object for the Function Raster Dataset.
Dim functionRasterDatasetName As IFunctionRasterDatasetName
functionRasterDatasetName=New FunctionRasterDatasetName()
' Specify the output file name for the new dataset (including the .afr extension at the end).
functionRasterDatasetName.FullName="c:\temp\ColorspaceConversion.afr"
functionRasterDataset.FullName=functionRasterDatasetName
' Initialize the new Function Raster Dataset with the Raster Function and its arguments.
functionRasterDataset.Init(rasterFunction, rasterFunctionArguments)
